I have packet loss, and randomly connection loss (but otherwise i have very good pings!) under windows 7 with two different computer with realtek 8111B and 8111E onboard chips. But there is no packet loss under windows xp with the same computers.
I tried old, new, and motherboard manufacturer's drivers, new windows 7 system without any antivirus software, disabled windows defender, in safe mode, but still the same. I have no router, just a modem directly plug into the pc.
Whats the problem? Windows 7 or realtek drivers/chips?
Can you help me?
